We are facing a severe performance issue with Ignite SQL select JOIN queries when using Order By clause. This occurs when the column used for Order By is not one of the columns in the where clause.
SELECT * FROM CACHE1 C1, CACHE2 C2 WHERE C1.JOINCol = C2.JOINCol AND C1.COL1 = 'someValue' ORDER BY C1.COL2 In this situation, it looks like the index available on the order by column (C1.COL2) is not used by SQL engine. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
